reclaims. (o1. saga-262) A great number of storm window fasteners have been constructed for the purpose of holding a storm Window in a partially open position. Some of these fasteners arepivoted to storm' windows and to. the-.frameand areprovided with a pivotal knee joint, Other fasteners comprise a bar pivoted to the Window and engageable. with a bracket on the frame. This latter type of bracket is usually considered disadvantageou because ofits tendency to rattle whenwind acts upon the window supported. It is the purpose of the present invention to provide a fastener construction of the rigid type which is free of the objectionable disadvantages previously encountered. I It is the object of the present inventionto provide a window fastener including a relatively rigid memberpivotally'connected to a storm window orthe like, and to provide a means of limiting the pivotal movementof this member. Accordingly by properly positioning a hookon the window frame, the swinging movement of the window acts to tighten the relatively rigid member against the hook; creatinga firm engagement between therelatively rigid member and the hook. A feature of thepresent invention lies in pro -viding a resilient relatively rigid member which is pivoted to the window so-as to pivot on a plane substantially perpendicular to the inner surface of the window and parallel to asideedge of the window. This pivotal movement is limited so that As a result the fastener will not rattle when thewindow is subjected to varying striking the same. I r i A further feature of the present invention lies in the provision :of a hook or recess in the relatively rigid member which may engage the bracket 0n the window frame to limit outwardpivotal movement ofithe window. This notch orhook forces of thewind faces downwardly so that as the windowis swung toward open position the notch will engage the window bracket over. which the rigid member slides it during outward'pivotal movement of the storm window.

A further feature of the present invention lies in the provision of a window fastener which may be detached in an extremely shortperiod of time to permit the storm window to be swung outwardly beyond its normal limitrwhen it is so desired, When the storm WiIIdOWdS close to its.

frame, or in almost closed position, the relatively rigid member may be easily detached from its tener tight when thestorm window is in closed position.- The relatively rigid arm or link may be flexed freely in looking the Window closed, thereby not only preventing rattling of; the fastener in closed position of the window, but providing ,a

leverage which will close the window tightlyin its frame. l r

A further feature of the present invention ,lies

in the fact that in closed position of the window the resilient linkor arm extends between two hook elements which extendinto the window and or arm. Therefore inorder to adjust. the spring tension tending to pull the window into closed position, it is only necessary to thread one of the hook elements into the windowa greater or lesser distance, thereby increasing or decreasing the spring tension tending to draw the window closed.

3 These and otherobjects and novel features of my invention will be more clearly and fully set forth in the following specification and claims.

In the drawing formingapart of my specification: a t t Figure 1 is a perspective view of the fastener in position connecting a storm window to its frame. I

Figure 2 is a side elevationalview, partly in section showing the position of the fastener when the storm window is in closed positionagainst its frame. i

Figure 3 is a front elevationalview taken from a position at right angles to Figure 2, showingthe storm window in closed position.

Figure 4 is a perspective view of the pivotele' .on the windowframe 22. this hook-shaped end 21 is best illustrated in Figures 1 and 2' of the drawing.

Figure 8 is an enlarged detail view showing. the manner in which the link or arm engages the pivot member when this pivot member restricts the pivotal movement of the arm.

The window fastener comprises" but few sepa-' rate parts and for this reason may be economically made and sold at an extremely low cost- The essential elements of the combination comprisean eye bolt pivoting member In of special construction, or its equivalent, a relatively rigid resilient arm or link II, a hook I2 arranged to act as anfulcrumfor the arm in closing the windew, and. a secondhook element l3 designed to lock the window in closed position. When these elements are properly placed, an extremely simple and effective window fastener is provided.

The eye bolt I preferably includes a threaded shank: Mwhich may be threaded into the sash I5" of the'storm window; indicated in general by the numeral- I6. This shank I4 terminates in a loop-shaped end I! which is provided with a pair of laterally extending shoulder bulges I9; These shoulder bulges I'El are arranged to limit relative pivotal movement of the link or arm II as will be later pointed out in detail. The link or arm II: is provided with a loopshaped head which encircles the lower portion of the loop end I1 of the eye bolt ID. This loop 20 is of such a size that it may pivot readily about the lower portion of the loop-shaped end H, but is limited in its pivotal movement by the shoulders I9. Thus in actual practice the arm Il may pivot until it is substantially normal to the inner surface of the storm window' I6, but can notpivot upwardly to a greater extent. The opposite end of the arm or link II from that supporting the loop end 20 is provided with a hook-shaped portion 2|. This hook-shaped portion faces downwardly when the armI'I is pivoted upwardly so as to engage the bracket I2 The construction of The bracket I2 may be formed as best illustrated" in'Figure5 of the drawing. This bracket comprises a shank 23 which is'externally thread-- arm I I in its proper relationship during the pivotal movement of the storm window and also serves to retain the arm in proper position when the window is closed. This bracket I2 may be 'used witha suitable washer if it is so desired, such as the cup-shaped washer 25, illustrated in Figure 6 of the drawing. The washer 25 is shown having a central opening 26 and a series of peripheral teeth 2T which may extend into the window frame 22 th hold the washer in its proper place.

In orderto lock the window-inclosed position a simple threaded hook I3 having a threaded shank 29 and a hook end 30 is engaged into the window frame I5. This hook I3 is designed to engage the arm or link II in closed position of the window so as to hold the window tightly closed. The spring tension tending to pull the Window closed may be adjusted by the position of the hook I3, and if this hook is threaded farther into the window sash I5, the arm or link I l is bent to a greater extent, thereby increasing the spring tension tending to pullthe window closed.

U The operation of my windowfastener is extremely simple. When the storm window is pivotally hung upon its pivotal supports, each side .of the sash. I5 is usually equipped with an eye bolt I!) from which depends a link or arm II.

This arm or link II is pivoted'upwardly and swung laterally so as to clear the hook I2 and to be engaged thereby. The lower end of the arm I'I may then be engaged in the hook I3 in the manner best. illustrated in Figures 2 and 3 of the drawing.

When it is desired to open the window the arms H are urged toward the window l6 and laterally a sulficient distance to disengage the arms from the hooks I3. The storm window It may then be urged outwardly either by forcingthe arms H outwardly or by engaging the window itself and pushing the same outwardly, the links II riding in the brackets I2. As the window pivots outwardly, however, the free ends of the arms II which are riding over the brackets l' z prevent downward movement of the ends of the arms, causing these arms II to flex. Thus if the window I6 is pivoted into its outer extreme position the hooks 2I snap into engagement with thehook brackets I2 under spring tension holding the window I6 locked in partially open position.

When it is desired to close the window it is necessary to exert sunicientupward force on the;

inner ends of the arms I I to-disengage the hooks 2| from. the hook brackets l2, whereupon the window may pivot inwardly. When thewindow approaches closed position they arms II are swung over the hook brackets I2 whiohact as a fulcrum to pull' the window tight against its frame. The arms II areordinarily flexed engaging the same with the hooks I 3to hold thewindow-locked closedi In describing the fastener, I have described a specific type of eye bolt, armand. hook construction to be used'in combination. While-the specific combination illustrated has advantages over any otherconstruction with which I am familiar,

it is possible that equivalent constructions may be used without departing from the spirit of my invention.

In'accordance with the patent statutes, I have described the principles of construction. and operation of my window bracket, andwhile I have endeavored to set forth: the best embodiment .thereof, I desire to have it. understood, -tha-t obresiliently urge said arm against said bracket as i the window is pivoted outwardly.
